You are not doing what you think you are doing, and it is impossible to notice on your own

She means it. She is not lying, and she is not exaggerating.

But her team has learned something else. When someone knocks, Anna looks up from the screen with an expression that says this is an interruption. She listens, but her fingers stay on the keyboard. Her answers are short. After a while, people stop knocking.

Anna describes her leadership entirely honestly, but what she describes is not what she does. And it is precisely that difference the American organizational researcher Chris Argyris spent a large part of his working life trying to understand.

Two theories about your own behavior

Together with the philosopher Donald Schön, Argyris formulated a distinction that has become one of organizational psychology's most cited ideas (Theory in Practice, 1974). Every person carries two different "theories" about their own conduct:

Espoused theory is the theory you say governs your behavior. It is the answer you give when someone asks how you act in a given situation: "I welcome criticism." "I listen before I decide." "I delegate and trust my team."

Theory-in-use is the theory that actually governs your behavior, visible in what you do rather than in what you say. It is the one your colleagues, team members and managers meet every day.

For most of us the two theories do not match. And here comes the decisive point, the one that makes Argyris's idea something more than an observation about hypocrisy: the gap is not deliberate. Anna is not being a hypocrite. Her espoused theory is sincere. The problem is that her theory-in-use is automated, learned, ingrained and therefore invisible to her.

Why you cannot see the gap yourself

That the gap is invisible from the inside is no accident. It follows from how self-knowledge works.

You have excellent access to your intentions, which is the raw material of your espoused theory. But you have surprisingly poor access to your behavior as others experience it: your tone of voice, your facial expression, how often you interrupt, how your "open questions" actually sound. That is exactly the pattern the research on self-assessments shows: we know our intentions, but the people around us see our actions. (Read more in our article on why self-assessments are unreliable.)

Argyris also made a discovery that surprised him. Studying thousands of managers and specialists, he found that almost all of them held the same espoused theory: they said they valued openness, honesty and learning. But under pressure, when something was at stake, when criticism was in the air, the vast majority acted according to an entirely different pattern: control the situation, avoid losing face, wrap uncomfortable messages in padding. Without knowing it.

In the article "Teaching Smart People How to Learn" (Harvard Business Review, 1991), Argyris showed that the pattern is strongest among high performers. People who rarely fail have never had to practice examining their own contribution to problems, so when something goes wrong the searchlight reflexively points outward.

What the gap sounds like day to day

The gap between espoused theory and theory-in-use is rarely dramatic. It sounds like this:

"I welcome feedback." But when a team member raises criticism, the explanation comes instantly: "Yes, but the reason I did it that way was..." The feedback has been answered, not received. The team member learns that criticism is indeed invited, but not taken in.

"We make decisions together." The meeting is called a dialogue, but the decision has in practice already been made. The questions asked are framed so that only one answer is reasonable. Everyone in the room can feel it, except the person running the meeting.

"I delegate." Responsibility is handed over with the words "you own this", but is followed by frequent check-ins, detailed opinions and corrections. What was meant as trust is experienced as surveillance.

Notice what the examples have in common: in every case the espoused theory is sincerely meant. None of these people would recognize themselves in the description of their actual behavior, and that is the whole point.

The way out: learning in several loops

Argyris distinguished between two kinds of learning, and later researchers have added a third loop.

Single-loop learning means adjusting the action when the result fails to appear. The thermostat is his classic image: if it gets too cold, the heat comes on. Anna notices that nobody brings her problems and therefore introduces a weekly meeting for exceptions. The action changes, but the assumptions behind it are left untouched.

Double-loop learning means questioning the governing assumptions themselves. Why does nobody come? What is it about the way I receive people that makes the door open only in theory? What am I signaling that I cannot see?

This is where real development happens. But there is a built-in catch: you cannot examine assumptions you cannot see. Your theory-in-use is by definition invisible to you, it is only visible from the outside. Double-loop learning therefore almost always requires a mirror you cannot hold up yourself: someone else's picture of how your behavior actually lands.

Triple-loop learning is the step beyond that: learning about your own learning. Here the question is no longer "which assumptions govern me?" but "how do I go about discovering such things about myself at all, and how can I get better at it?"

For Anna, the three loops look like this. Single-loop: nobody comes to me, so I introduce a weekly meeting. Double-loop: perhaps there is something in how I receive people that closes the door, what do others see that I do not? Triple-loop: I only gained that insight because someone held up a mirror. How do I make sure the mirror was not a one-off? What structures do I need, recurring feedback, people with a mandate to say the uncomfortable thing, in order to keep seeing what I cannot see myself?

In other words, triple-loop learning changes not only what you do or what you assume, but your relationship to your own self-knowledge: from something you believe you already have, to something you actively fetch from the outside, again and again.

What this means for how behavior should be measured

Argyris's distinction has a direct consequence for every tool that tries to describe how people function:

A self-assessment measures your espoused theory. It captures your intentions, your self-image, your sincere description of how you act. It is honest, and insufficient, because it measures the wrong theory.

The outside view captures your theory-in-use. It is the colleagues, team members and managers who meet your actual behavior every day, the tone of voice, the interruptions, the body language at the door.

That is why the IDI behavioral profile is based on how the people around you perceive your behavior, not on how you describe it yourself. Not because your self-image is uninteresting, but because it, exactly as Argyris showed, systematically describes a different theory from the one you actually use. The difference between the two is not measurement error. It is the insight itself.
